South Korean President Park Geun-hye received no treatment from her medical staff on the day of a deadly ferry disaster in 2014, a former presidential nurse said Wednesday, amid persisting rumors she might have undergone plastic surgery.

The Army nurse, identified as Capt. Cho, who has been in the US for training at an Army hospital in Texas, also said in a telephone interview that neither she nor other medical staff visited Park's residence on April 16, 2014, when the ferry disaster happened.

Her remarks are in line with what another former presidential nurse, identified as retired Capt. Shin, said about what happened on that day. Shin said in a recent media interview that she performed her routine duties but didn't see the president that day.

Asked whether Park usually received Botox wrinkle treatments or other cosmetic procedures, Cho said, "Not that I know of." She side-stepped questions about whether Park has usually received various nutritional injections or used outside medical facilities, citing confidentiality about patients.

Rumors have persisted that Park might have undergone plastic surgery or other medical procedures on the day of the ferry disaster, which detractors allege could have led to her failure to properly cope with the sinking of the ferry Sewol that left more than 300 passengers dead or missing.

The rumors came to the fore recently in the wake of a separate corruption scandal surrounding allegations that a long-time confidante of Park exercised huge influence over her and state affairs, and amassed ill-gotten wealth. Park has offered to step down over the scandal. (Yonhap)
